Y Application February 25, 1936, Serial No. 65,739

3 Ciaims.

This invention relates to a strainer for drain pipes for eaves troughs.

The invention has for its object to provide, in a manner as hereinafter set forth, an effective and economical strainer constructed entirely of interengaging lengths of wire and which may be expeditiously inserted in the mouth of the vertical drain pipe of an eaves trough.

A further object of the invention is to provide, in a manner as hereinafter set forth, a strainer for the purpose referred to formed of individual spaced wires looped together intermediate their ends and connected together at their upper ends in spaced relation without the Iaddition of a separate tying or a separate spacing means for the wires.

The invention not only embodies the objects and advantages of the form of strainer disclosed by my application filed April 20, 1935, Serial No. 17,516, but has for its further object to` provide a skeleton strainer formed of a series of spaced wires having inherent means intermediate their ends for spacing and connecting them together and interengaging inherent means at their upper ends for directly spacing and connecting them together thereby overcoming the employment of a coupling in the form of an annulus as is employed in the form of strainer disclosed by the application aforesaid.

Further objects of the invention provide, in a manner as hereinafter set forth, a strainer for the purpose referred to which is simple in its construction and arrangement, strong, durable, compact, readily assembled, thoroughly ecient in its use, and inexpensive to manufacture.

With the foregoing objects in View and to others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specically 40 referred to and are as illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations, and modications may be resorted to which fall within the scope of the invention as claimed.

In the drawing:

Figure l is a side elevation of the strainer,

Figure 2 is a top plan view thereof,

Figure 3 is a fragmentary view in side elevation illustrating the manner of connecting the upper ends of the wires together,

Figure 4 is a fragmentary view in perspective illustrating the form of the intermediate stretch of each of the wires, and

Figure 5 is a top plan view illustrating the form of the upper end of each of the wires.

The strainer is of annular `cross section and formed of a series of spaced individual wires 6 arranged in the form of a skeleton body having its upper portion I of bulbous contour and its lower portion 8 substantially of uniform diameter.

Each wire 6 includes a lower straight upstanding stretch 9, an intermediate horizontal stretch i0 disposed substantially at right angles to the upper end of stretch 9 in an anti-clockwise direction and an outwardly curved upper stretch II terminating at its upper end into laterally directed substantially horizontally disposed curved portions I2 and I3 formed integrally with the upper end of the wire and providing oppositely directed hook members for co-operation with an attachment to adjacent wires.

The intermediate stretch I0 consists of a p0rtion l which inclines downwardly relative to the upper end of stretch 9 and merges into the inner side of a U-shaped portion I5 olfset with respect to the portion I4.

The stretches i0 maintain the stretches 9 in spaced relation. Each stretch 9 of a wire S eX- tends through the U-shaped portion I5 of an intermediate stretch i0 of an adjacent wire 6. The lower end of the stretch II of each wire 6 is formed with an incurved portion, as at IS which merges into the U-shaped portion I5 of said wire The upper end of each stretch 9 is arranged within a U-shaped portion I5 of an intermediate stretch. The portion I4 of each intermediate stretch seats on av side of the portion I5 of an adjacent stretch and opposes the outer side of the incurved lower end I6 of a stretch II which merges into that side of the portion I5 upon which a portion I4 seats. The stretches I0 connect the stretches 9 with the stretches II and maintain the wires in spaced relation. The mani,

ner in which the stretches I0 are formed, their relation to the stretches 9 and II and the manner in which the lower ends of the stretches II are formed provide for the wires 6 to interengage intermediate their ends and for coupling the wires 6 together.

The hookparts I3 at the upper ends of the stretches ll are substantially closed and have the curved portion I2 extend therethrough whereby the upper ends of the wires 6 are connected together and the stretches II are maintained in spaced relation.

The stretches I0 offset the stretches II relatively to the stretches 9 whereby a stretch II of one Wire 6 will have its lower end aligning substantially with the upper end of a stretch 9 of an adjacent wire 6. The stretches ll project outwardly with respect to the upper ends of the stretches 9.

The stretches l0 provide spacers for the Wires 6. The hook-parts I3 provide couplers for the upper ends of the stretches Il and due to the arrangement of the curved parts I2 and hookparts I3, the upper ends of the stretches Il are disposed in a circular row. The stretches 9 form what may be termed a skeleton flexible extension which may be forced down into the upper end of the drain pipe which is connected to the eaves trough in a manner well known in the art.

The manner in which each of the Wires is constructed provides for assembling, by hand the wires in cage formation with the wires connected together intermediate their ends and directly secured together at their upper ends.

What I claim ist- 1. An eaves-trough strainer comprising a plurality of upwardly extending wires, said wires formed to provide a lower cylindrical portion and an upper bulb-shaped portion, the upper end of each of said wires terminating in laterally extending curved portions formed integrally with the upper end of the wire and formed to provide oppositely directed hook members for cooperation with and attachment to adjacent Wires.

2. An eaves-trough strainer in accordance with claim 1 wherein each of the said wires is formed to provide an intermediate substantially horizontal portion, the ends of said intermediate portion terminating in curved portions, said curved portions adapted for co-operation with and attachment to adjacent wires.

3. An eaves-trough strainer consisting of a plurality of upwardly disposed Wires, each of said wires having a substantially vertical lower portion, an inwardly curved upper portion and means formed integrally with the upper end of the wire for co-operation with and attachement to adjacent wires, said means including laterally extending curved portions forming oppositely directed hook members.
